Peyote is a small, spineless cactus native to the southwestern United States and Mexico, used traditionally in indigenous religious rituals. The plant contains mescaline, a psychoactive alkaloid, and is known for its psychoactive effects when consumed as part of ceremonial practices or as a hallucinogenic substance. In general usage it also refers to the psychedelic experience or the pot-plant itself, often in historical or ethnobotanical contexts.
